Subject: [PATCH] Do no isolate in case of emergency or severe problems
This patch changes local-fs.target and systemd-fsck to not use
"isolate" when going into emergency.
This fixes https://bugzilla.redhat.com/show_bug.cgi?id=810722
The motivation is, that when something wents wrong, we should
keep everything as it is, to let the user fix the problem. When
isolating we stop a lot of services and therefore change the
system heavily so that it gets harder for the user to fix.
An example is a crypted partition. When the fsck in a crypted
partition fails, it previously used "emergency/start/isolate"
which stops cryptsetup. Therefore if the user tries to fsck
e.g. /dev/mapper/luks-356c20ae-c7a2-4f1c-ae1d-1d290a91b691
as printed by the failing fsck, then it will not find this
device (because it got closed).
So please apply this patch to let the user see the failing
situation.
Thanks!
[zj: removed dead isolate param from start_target().]

The vacuum code used to stop vacuuming after one deletion, even
when max_use was still exceeded.
Also make usage a uint64_t, as the code already pretends it is one.

Subject: [PATCH] core: ensure LSB Provides are handled correctly
Let's say you have two initscripts, A and B:
A contains in its LSB header:
Required-Start: C
and B contains in its LSB header:
Provides: C
When systemd is parsing /etc/rc.d/, depending on the file order, you
can end up with either:
- B is parsed first. An unit "C.service" will be "created" and will be
added as additional name to B.service, with unit_add_name. No bug.
- A is parsed first. An unit "C.service" is created for the
"Required-Start" dependency (it will have no file attached, since
nothing provides this dependency yet). Then B is parsed and when trying
to handle "Provides: C", unit_add_name is called but will fail, because
"C.service" already exists in manager->units. Therefore, a merge should
occur for that case.

Subject: [PATCH 1/2] readahead: chunk on spinning media
Readahead has all sorts of bad side effects depending on your
storage media. On rotating disks, it may be degrading startup
performance if enough requests are queued spanning linearly
over all blocks early at boot, and mount, blkid and friends
want to insert reads to the start of these block devices after.
The end result is that on spinning disks with ext3/4 that udev
and mounts take a very long time, and nothing really happens until
readahead is completely finished.
This has the net effect that the CPU is almost entirely idle
for the entire period that readahead is working. We could have
finished starting up quite a lot of services in this time if
we were smarter at how we do readahead.
This patch sorts all requests into 2 second "chunks" and sub-sorts
each chunk by block. This adds a single cross-drive seek per "chunk"
but has the benefit that we will have a lot of the blocks we need
early on in the boot sequence loaded into memory faster.
For a comparison of how before/after bootcharts look (ext4 on a
mobile 5400rpm 250GB drive) please look at:
http://foo-projects.org/~sofar/blocked-tests/
There are bootcharts in the "before" and "after" folders where you
should be able to see that many low-level services finish 5-7
seconds earlier with the patch applied (after).

- Add improve-readahead-spinning.patch: improve readahead
performance on spinning media with ext4.
- Add fix-journal-vacuum-logic.patch: fix vacuum logic in journal
(bnc#789589).
- Add fix-lsb-provides.patch: ensure LSB provides are correctly
handled if also referenced as dependencies (bnc#809646).
- Add fix-loopback-mount.patch: ensure udevd is started (and
therefore static devices are created) before mounting
(bnc#809820).
- Update systemd-sysv-convert to search services files in new
location (bnc#809695).
- Add logind-nvidia-acl.diff: set ACL on nvidia devices
(bnc#808319).
- Add do-no-isolate-on-fsck-failure.patch: do not turn off services
if fsck fails (bnc#812874)
- Add wait-for-processes-killed.patch: wait for processes killed by
SIGTERM before killing them with SIGKILL.
- Update systemctl-options.patch to only apply SYSTEMCTL_OPTIONS to
systemctl command (bnc#801878).

Subject: [PATCH] shutdown: correctly wait for processes we killed in the
killall spree
Previously we simply counted how many processes we killed and expected
as many waitpid() calls to succeed. That however is incorrect to do.
As we might kill processes that are not our immediate children, and as
there might be left-over processes in the waitpid() queue from earlier
the we might get more ore less waitpid() events that we expect.
Hence: keep precise track of the processes we kill, remove the ones we
get waitpid() for, and after each time we get SIGCHLD check if all
others still exist. We use getpgid() to check if a PID still exists.
This should fix issues with journald not setting journal files offline
correctly on shutdown, because we'd too quickly proceed from SIGTERM to
SIGKILL because some left-over process was in our waitpid() queue.
